Gene : AT4G35540 A. thaliana

DB identifier  ? AT4G35540 Secondary Identifier  ? locus:2127953
Brief Description  POLLEN-EXPRESSED TRANSCRIPTION FACTOR 2
TAIR Computational Description  POLLEN-EXPRESSED TRANSCRIPTION FACTOR 2;(source:Araport11)
TAIR Curator Summary  Encodes a novel plant-specific TFIIB-related protein that can interact with TBP2 and bind DNA. It can also form a homodimer and interact with the subunits of RNA polymerases. Mutant pollen fails to germinate.
TAIR Short Description  zinc ion binding;transcription regulators
TAIR Aliases  PTF2

Type Comment Proteins
PTF2_ARATH developmental stage In developing pollen grains, expressed in the vegetative nuclei at the early binucleate stage and during the second pollen mitosis. Expression significantly decreases at the late trinucleate developmental stage. Not expressed in released mature pollen grains, germinating pollen grains and pollen tubes.
PTF2_ARATH function Plant-specific TFIIB-related protein that plays important roles in pollen germination and embryogenesis, possibly by regulating gene expression through interaction with TBP2 and the subunits of RNA polymerases. Binds double-stranded DNA in vitro.
PTF2_ARATH tissue specificity Expressed in shoot apical meristems, root tips, primordia of lateral roots, inflorescences, developing pollen grains and embryos.
